Variation in distance from critical point captures variation in antibody decay between vaccines and demographic groups. Plasma cell survival curves were simulated for μξ−4/3=−0.2,0,0.2,0.4,0.6,0.8,1 (all other parameters are as in Table S1). Left panel: survival curves normalized by t=0 (black lines), compared with the empirical survival curves from Figure 1A, upper panel. Middle panel: scaling of survival curves with log43(TA). Simulated survival curves (black lines) and empirical survival curves from Figure 1A, plotted against log43(TA) with A=0.5year corresponding to the inflection point where long-lived plasma cells emerge. Right panel: survival curves normalized by their logarithmic range (black lines), compared with the empirical survival curves.
